We stayed at the Muse Condo during our first stay in Bangkok and absolutely loved it. The host was communicative and responsive from the start. We asked him to arrange a private car from the airport, as we were arriving late and didn't want to deal with the hassle of a taxi. He did so with no trouble at all.
The Sukhumvit neighborhood is residential, offering a variety of restaurants, coffee shops, bars and stores. It was a great neighborhood to stay in, as it's a quiet place to retreat to after a long day in the sensory overload of Bangkok.
We especially loved the rooftop pool - the view is stunning and the atmosphere is relaxing. Additionally, the condo has a concierge/tuk tuk service that helped us to call a taxi when it was pouring rain on the day of our departure.
Overall, we loved our stay and would highly recommend to anyone coming to Bangkok, especially those who want a more peaceful stay after long days and nights of exploring.
